<p>Operating a metering device for supplying a reactant to a catalyst associated with a combustion unit comprises, starting from a putative steady state of the catalyst and/or combustion unit, determining a steady-state reactant supply value and correcting this with a dynamic correction coefficient. An Independent claim is also included for apparatus comprising means for determining the steady-state reactant supply value and correcting it with a dynamic correction coefficient.</p> |
